Be honest. They are looking for your ability to communicate fluidly and in a sociable way. Treat it as talking to a professional friend that you haven't seen in a long time. Make the interview conversational. They value interpersonal skills more than any experience. They believe they can train anyone to be an excellent recruiter as long as they are trainable at the very least.
People that make it a habit to comment on every candidate's ethnicity, imitate accents and voluntarily discriminate based purely on language or religion. I then gave an example of me having a conversation with a former colleague who kept doing that and how it wasn't a good thing and blabla. Keep in mind that "INCLUSIVITY" is one of the core values Coveo has on their careers website AND in the documents you'd receive in preparation for the interview. I received the feedback a couple of days later after asking thrice and they said that this made them feel really "uneasy".
